FUNCTIONAL DESCRIPTION

All data given in this chapter are typical values, except

when otherwise specified.

Supplies

LINE INTERFACE AND INTERNAL SUPPLY (PINS LN, SLPE,

REG AND VBB)

The supply for the TEA1097 and its peripherals is obtained

from the line. The IC generates a stabilized reference

voltage (Vref) between pins SLPE and GND. This

reference voltage is equal to 3.7 V for line currents lower

than 18 mA. It than increases linearly with the line current

and reaches the value of 6.1 V for line currents higher than

45 mA. For line currents below 9 mA, the internal

reference voltage generating Vref is automatically adjusted

to a lower value. This is the so-called low voltage area and

the TEA1097 has limited performances in this area

(see Section “Low voltage behaviour”). This reference

voltage is temperature compensated.

The voltage between pins SLPE and REG is used by the

internal regulator to generate the stabilized reference

voltage and is decoupled by means of a capacitor between

pins LN and REG.

This capacitor converted into an equivalent inductance

realizes the set impedance conversion from its DC value

(RSLPE) to its AC value (done by an external impedance).

The IC regulates the line voltage at pin LN and it can be

calculated as follows:

where:

Iline = line current

Ix = current consumed on pin LN (approximately a

few

µA)

ISLPE = current flowing through the RSLPE resistor.
